Airworthiness Directive · Amendment 39-21376 · Fuselage
Airbus SAS Airplanes
This AD applies to Airbus SAS Model A350-941 airplanes, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2020- 0109, dated May 15, 2020 (EASA AD 2020-0109).
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 airplanes. This AD was prompted by a report that during the assembly of a certain section of the fuselage, the gaps found on self-aligning nuts for eight fasteners were out of tolerance. This AD requires a rotating probe test of all fastener holes located in the affected area for any discrepancies, an eddy current inspection of the surrounding flange for any discrepancies, a detailed inspection of certain frames for any discrepancies, and corrective actions if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, EASA AD 2020-0109.
(1) The “Remarks” section of EASA AD 2020-0109 does not apply to this AD.
(2) Where paragraph (2) of EASA AD 2020-0109 specifies actions if “any discrepancy is detected, as defined in the SB,” for this AD a discrepancy is defined as any crack or damage.
(3) Where Airbus Service Bulletin A350-53-P057, dated February 21, 2020 (referenced in EASA AD 2020-0109), specifies Airbus task A350-A-53-XX-P057-01001-720A-A and task A350-A-53-XX-P057-02001-720A-A, for instructions for installing the new fasteners, and those instructions specify to refer to “ASR A350-A-20-51-01ZZZ-25BZ-A,” for the purposes of this AD, the correct reference is “AMM Maintenance Procedure A350-A-20-51-01ZZZ-25BZ-A.”
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
